Romans 6 reveals the union and identification we have with Christ, in Christ. The main thrust of v.5-10 is to reiterate that reality. Every verse from 2-11 points out thatwe are dead in Christ. We are not free to sin but from sin. As followers of Christ, our union with Him means that we will also die only once (as He did) and be resurrected (as He was). Oh how great is God's grace and how marvelous His mercy!
